FRANKLIN A. UMS'IED, OF CHICAGO, ILLINOIS.

CARPET-SWEEPER.

Specification of Letters Patent.

Patented May 2, 1916.

Application led J' uly 9, 1915. Serial No. 38,855.

To all 'whom t may concern Be it known that I, FRANKLnT A. Uivrs'rnD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification. This invention relates to improvements in carpet sweepers and one of theI objects of the invention is to simplify the construetion of the same and produce a carpet sweeper which will be simple, durable, light, cheap and of a rigid construction.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substani tially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating the invention, and in which:

Figure 1 is a central vertical transverse sectional view of an improved sweeper of this character constructed in laccordance with the principles of this invention. Fig. 2 is a top plan view of one end of the sweeper. Fig. 3 is an enlarged detail horizontal sectional view of one corner of the sweeper showing the manner of securing and holding the bumper in position. Fig. 4 is an enlarged detail elevation of one corner of the sweeper frame showing the bum per receiving notch.

Referring more particularly to the drawing, the numeral 10 designates a single piece of sheet material such as metal bent into shape to form the top and sides of the casing. The ends 11 of the casing are formed of sheet Vmaterial each provided with a flange 12 at the top thereof and projecting laterally therefrom so as to extend `under the end of the top 10, and these parts are secured together in any desired or suitable manner such as by means of spot welding 13. The casing thus formed may beof any desired size and coniiguration and the corners are secured together in Vany suitable manner preferably by extending a portion of the cover 10 adjacent the front and rear wheels of the sweeper so as to project a short distance beyond the ends 11 to form a projecting ear 14, and this ear is provided with an open recess 15., The ends of the end pieces 11 adjacent the projecting portions 14 of the cover 10 are deflected laterally as at 16,J see particularly Fig. 3, so as to rest against the ears 14, and the extremities of the projections 16 are also notched as at 17 to correspond with the recesses 15. These portions of the cover and ends are secured together preferably by means of fastening devices 18 in the form of bolts passing through registering apertures therein and nuts 19 secured to the bolts.

The end portions 11 are provided with recesses 20 which open through the lower edge thereof to receive the core 21 of the brush 22.

Extending' across the ends of the casing, and parallel with the end portions 11 thereof are wheel guards 23, constructed of any suitable sheet material and are held spaced from the end portions 11 by means of the ears 14 and the deflected portions 16 of the end portions 11, and these guards 13 are secured in position by means of the fastening bolts 18 which extend through the extremities 24 of the guards and which latter are deflected to rest against the front and rear face of the casing.

The brush 22 is rotatably supported preferably by the wheel guards 23 which latter are provided with suitable bearings, in which the projections 25 on the core 21 of the brush are journaled and the brush is provided with a friction disk 26 at each end thereof, which disks are positioned between the respective pairs of wheels 27, as is usual. in sweepers of this character.

The wheels 27 are each mounted upon an axle 2S, constructed of spring material and these axles extend through enlarged openings 29 in the end portions 11 so as to give the necessary spring movement to the wheels and to allow the casing together with the brush to be pressed downwardly toward the floor during the operation of sweeping.

- The wheels 27 are mounted on the outside axles, a bar or rod 31, which is provided with a bifurcated extremity 32 in which bifurcation the axle 2S is seated the extremities 33 of the arm are deflected around the axle so as to'hold the parts against dislocation. The other extremity of the bar or rod 31 is loosely positioned within a seat 34 formed in the casing 10 which seat is formed by offsetting a portion of the casing. These portions are offset from the inside of the casing so as to form projections extending from the outer face of the casing and one on each side of the machine, and these projections form the stops or bumpers against which the socket 35 of the handle bail 36 strikes, when the bail is in a folded position, the offset portion 34 serving the double function of a seat for the anchor bar 31 and a bumper for the handle bail. These axles 28 rest upon the bo'ttoins of the openings 29 and the centrally arranged bars or rods 31 tend to hold the axles in position while the axles in turn, being'of an velastic or yieldingnature, hold the ends of the barsor rods 31 seated -in the recesses formed by the offset portions 34.

A bumper 37 in the form of a band is provided and surrounds the casing on the outside thereof, at a considerable distance from the base ofthe casing and this bumper '37 may be held in position against displacement in any suitable or desired manner, preferably by notching the corners of the wheel guards 23 to form a recess, into which a portion of the band is seated. These recessesare formed preferably by cutting `the material on Veach side of the corner `to vform a portion 38, which is partially severed from the wheel guards. 'and the portion which is thus partially severed is located in alinement with the recess 15 and the corresponding notch in the end piece 16. The partially severed portion is then deflectedinwardly as shown more clearly in Fig. 3 to form a recess 39.

Thevbrush 22 is located preferably at the middle of the casing and extends entirely thereacross, and on each side of the brush is arranged a dust pan 40, which is also preferablyconstructed of sheet material and is of any desired size and configuration.` Each of the pans 40 is pivotally supported adjacent one edge as at 41, and an operating handle or lever 42 is provided for swinging the panabout its pivot. This handle 42 is preferably pivotally connected as at 43 with a `portion of the pan and extends through a slot 44 in the top of the casing and the projecting extremity of the handle 42 is deiected as at 45 to provide. a convenient means for operatingthe latter.

A spring 46a is connected with the pan and the handle and tends normally to hold the pan in ai closed position. The bumpers against which the pans 40 abut when in a "clsedfposition are preferably formed by bending the edges of the front andrear of the casingat the bottom thereof back upon itselfas at 46,\for any suitable distance to form a reinforce for the edge of the casing and then deflecting the free extremity o'f'this bent portion laterally 'as at 47 to form a ledge against 'which the Vedge of the 'pan strikes.

If desired inorder to hold lthehandle bail in an upright position when the sweeper is not in use, ortionsoffthe end pieces 1'1 may be deflected) or offset as at 48 to form projecting ribs-between which a notch 49 is Yarranged and into which notch the handle bail springs when the latter is`raised.`

l/Vith `this improved'construction it will be manifest rthat the entire sweeper is `constructed of metal and that there is no wood :present ingthis structure, with `the exception of the core of the brush, with the 'result that notonly axsiinplefand light structure will be produced but the frame when thus 'constru'cted.willbe'v rigid.. and durable and inexpensive ;to manufacture.,

. While -tlie preferred form of `construction has `been herein shown vand described, it is understood thatrvarious Ychanges may be made inthe details of construction andin'the combination 'and arrangement of the several parts without departing from the spirit of this invention.
